IMPROVEMENT IN HORSE 'HAY-roars.'

To ALLWHoM-lfr MAY coNcERN;

Be it known that I, IETER A. MOWEBS, ofGleversburgQ-of Crawford county, and .Stateof Pennsylvania,

4have invented a newland improved Horse HayfFork; and I 'do hereby ydeclare'tl'e following to be afnll, clear, i

and exact description of the same, reference being'h'ad to the accompanying drawing,whieh forms part 'of this specication.

The subject of. my infve'ntlon is ,a fork constructed `with two or more hinged prongs, geared together soxas to cause them to move in unison, and adapted-fte clasp the body 'f hay which they enter.

The necessary lmotion is-eommunicated to-the prongs vby a suitable lever, which may be rigidly attachedl to one of theprongs themselves, 'or to a segment-pinion gearing with the cog-segmentsor their-heels; In the drawingsv Figure 1 represents a vertical section at n; x, fig. 2,; and Y Figure Zavertical section at y y, figtl, of a two-pronged fork illustrating my invention.

The'two parts,- A'A, 'of the frame are -eonnectedb'y anysuitable number of bolts", asa afa? as: B .Care-e. pair of prongs fulerumed uponthe; bolts aalrandformed-o'n their heels withcogged segments v c, gearing with a segment-pinion, al, vupon al lever, D. E is a latch,'aet ed lon bya spring, rF, andv'serving to hold the'lejvei when `the prongs are closed, as shown in the drawing.V Gr `is the't'ripping-cord, t4 retra'etthe latch Eran'cl th-us releaseY the lever D when the load-iste be discharged.4 H represents the hoisting-rope. v

h Figures and 4 are respectively a-fxcntiand-asifleelevation of a similarfo'rlt; whichithefoperatngflever, Dfis notattached directly to its pinion, d', but is mounted upon a sq'uarofupon the projectingendof the pivot a4, on which the said .pinion is rigidly keyed. lThis lever'Dlis bennes represented in `fig. 4iso-as to-engag'o with the catch E within the frame, and the operation-is the 'same as before described.

Figure 5 is a vertical section, and i e v Y Figure 6 a side elevation of arfork,iin which the same invention is embodied, but4 the pinion entirely dispensed `with, the lever D2.bei`ng rigidly attached to theheel of the. piion'glB.

' The latch E may be mounted on' the lever, and hold a trigger, I, also p ivoted in the end of the leven-and hooking' into a link, J, attached to the end oi' the hoisting-rope Hf. I n' i P is apulley, vunder which the rope works. In this case the load is discharged by pulling thecord G,' which releases the Atrigger I, and causes it to let' Ago the'rope H', when the forkis opened Vby the gravity of .thehay and discharges thelload. The position vot" the -parts at this time' is Ashown in red. The blue lines represent the parts in position toseize the hay. Y I o 4- v I t The points being once inserted willl be'driv-en into the hay by ther power of the horse-drawing on' the hoistiug iope Hpsothat the fork is set or fed into lthe hay, as well` as elevated; by horsefpowenl l In the other illustrations the fork is drivenl` into Vthe'hayby the ;han'd ofthevoper'ator applied to the level' A threeor four-pronged fork maybeinade onprecisely the same-principle, by keying the prongs in pairs" or to. one or both ofthe shaft-s a a?. v Instead of having the segments b and c` gear together, the pinion UZ, gearing with thevsegm'entfb, may turn the segment -c in the opposite direction through an intermediate pinion. i

- Having thus'described my invention, what I clain as, ne\v,5^and desireto secure byLetters Patent, is asfollows:

The pair of grasping-prongs B (l, operated in' unison by means ofieogged segments '11 Vc,"inA combination with ajlever to open or close them, substantially as and fo'r thepurposes explained.
